Nowadays, transportation, because of the intense
need to be delivered to the market in terms of both products and commercial and
tourist activity in our times, is one of the vital sectors. Especially in
countries in which a large portion of the road transport and transport services
such as Turkey, road transport has become very important. This study made an
application related to collect the medical waste from hospitals in Eskişehir,
Turkey. In order to collect waste regularly, the route is extremely key factor.
In this study, a mathematical model is demonstrated to make an efficient route
path. The locations of hospitals are defined and the distances are calculated
in digital map. Subsequently, the monthly data are compared with the routes of
the vehicle that are suggested by developed model. In this article, a
generalized multi-objective vehicle routing model with collecting the medical
wastes from hospitals in Eskişehir is proposed. Some methods have been used to
combine the objective functions. Seven methods are applied to the mathematical
model and the results are compared to determine the most effective method to
combine the objective functions. The mathematical model has 2 objective functions.
These are to collect the medical waste by covering a minimum distance and
driving with minimum speed per hour.
